[antlr-interest] ANTLR newbie - Passing custom objects to Parser

[Rajiv Kadayam]

I;m trying to implement an boolean expression interpreter for which 
the arguments will be java objects and will have to be specified 
external to the expression. The expression will have "variable" names 
that point to these objects via hashmap. I just need to be able to 
pass this hashmap to the Parser/Lexer and then when it does the 
parsing/interpreting, the grammar could pick it up from the hash-map.

However I'm not sure how I'd pass the hashmap to the generated 
Lexer/Parser java objects.

Any help greatly appreciated. Also does anyone have any experiences 
writing a simple boolean expression evaluator/interpreter ?

Thanks in advance
Rajiv
